33. Detect Circular Pattern Match

#include <stdio.h>
#include <stdint.h>

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    uint8_t result = 0;
    for (uint8_t i = 0; i<16; i++)
    {
        uint16_t temp = (reg << i) | (reg >> (16 - i));
        if (target == temp)
        {
            result = 1;
            break;
        }
    }
    return result;
}

int main() {
    uint16_t reg, target;
    scanf("%hu %hu", &reg, &target);
    printf("%hhu", is_circular_match(reg, target));
    return 0;
}
